The Liberal MPP candidate whose narrow election night victory in Thornhill was overturned because of a tabulation error, is requesting a judicial recount over what her campaign team is calling “various inconsistencies” in the final tallies.

Sandra Yeung Racco thought she had defeated her opponent, Conservative incumbent Gila Martow, by a slim 85-vote margin in the riding just north of Toronto when Elections Ontario announced its unofficial results late Thursday evening.

But Elections Ontario reversed the result Friday after the official tabulation was conducted, citing that the numbers submitted by poll officials by telephone Thursday were different in some instances that what was written on the forms submitted. As it turned out, Ms. Martow had defeated Ms. Yeung Racco by 85 votes, rather than the other way around.

The changes does not affect the status of the Liberal majority. The party now has 58 seats to the Conservatives’ 28.

Milton Chan, the campaign manager for Ms. Yeung Racco, said the candidate is requesting a judicial recount “because of the uncertainty” associated with the process.

“We were given one set of results on election night. We were given another result the day after,” said Mr. Chan. “We are not saying that we think we have won or we think we have lost. We are saying that when the result is so close, everyone deserves to feel confident that the final result is accurate and that voters got the MPP that they voted for.”

Elections Ontario attributed the differences to “transpositions and other minor clerical errors.”

But Mr. Chan said there were 13 polls that experienced changes in the final tallies for both Ms. Yeung Racco and Ms. Martow, and that the final result was inconsistent with notes taken by the Liberal candidate’s team of scrutineers at each poll.

He said Ms. Yeung Racco would look to file her request for a recount as quickly as possible.

According to Elections Ontario, a request must be made within four days of the official tabulation if a candidate believes ballots were counted improperly, there was an incorrect statement of the number of ballots cast, or the returning officer has improperly tabulated the vote. If the judge accepts the request at a hearing, the recount must take place within 10 days.

Ms. Martow says she never planned to request a recount when it was thought she’d lost because her scrutineers didn’t notice anything alarming when ballots were counted.

“None of this had anything to do with ballots. This is all strictly data entry,” she said. “If they’re suggesting improprieties, then I would suggest the impropriety that took place was in your favour. If anyone should be wondering why was something improper being done, then I think it should be my camp, and we’re certainly not suggesting anything. We’re saying it’s human error. That’s what we’re told, and we believe it’s human error.”

Ms. Martow said she was shocked by the revelation she had won the riding after tasting defeat the previous night. While she says she stayed calm after thinking she had lost, she was moved to tears when her campaign manager phoned with the good news.

“I honestly didn’t believe her for the first little bit,” Ms. Martow said. “My eyes started to well up. I guess I had been holding in all this emotion since Thursday night.”

But for Ms. Yeung Racco, it’s been an opposite “roller-coaster” of emotions.

“It was announced on all major networks that she was elected and then less than 24 hours later she was told that she was not elected,” said Mr. Chan. “It is has been difficult for her and she’s obviously disappointed. She just wants to assure herself that if she has lost, it’s for sure she has lost. It’s not through any mistakes, through any calculation errors.”
